date: Wed Sep 15 09:52:38 2004 from: Phil Jones subject: Some DTR info to: Adrian Simmons Adrian, I've been in touch with the Asheville folk. There was some confusion there as I'm working with them on 2 things (trying to get their DTR data and also a simple comparison of GHCN/CRU/NASA mean temperature datasets). Have a look at these plots. They give an idea of coverage. They are working on improving the coverage and hope to have a dataset in a few months. I could get the current version, but they tell me it will be significantly improved. Do we want to wait? Depends on time available over the next few months I guess. I'm away much of the next 6 weeks and then have to work with Kevin on putting together a first draft of the IPCC Chapter on the Observations. Let me know how you're fixed for the months up to Christmas. Do you want to be involved in the IPCC chapter as a Contributing Author - or to review our first draft (early next year). We have our first meeting the week after next and we will decide on the CAs who'll assist us and also on friendly reviews of the zeroth order draft. Hope the revisions of the JGR paper are not too onerous.

We have only used mean temperature for the GHCN/CRU comparison, so no DTR. However, I did find some DTR analysis I did last October 22-24. I've attached several related graphics files. [Russ, I found these on Argus in ~dwuertz/projects/max_min/adjusted/prelim. This analysis used a preliminary version of the recently updated GHCN max/min data set (I believe), and adjustments made by the recent Menne/Williams method (I believe).] Are these the results Phil is interested in? If so, I can probably locate the ASCII data that correspond to the attached maps of DTR trends. I will send those in a subsequent email after while if I do not hear from you, just in case this is what you want. If I'm sending you the wrong stuff, please let me know along with more detail next time, and hopefully I'll get it right. I see that it's pub time there, so I may not hear from you until morning.
